The main difference between autoclaved aerated concrete (AAC) and non-autoclaved aerated concrete (NAAC) blocks is the curing process. AAC blocks undergo high-pressure steam curing in an autoclave, while NAAC blocks develop strength without high-pressure autoclaving, using a suitable ambient, moist, or other non-autoclave curing method.

A 30 m³/day non-autoclaved aerated concrete (NAAC) block production line should be configured around accurate material batching, controlled foam generation, efficient mixing, suitable molds, reliable cutting, and sufficient curing space.

A low-cost mini NAAC plant can be a practical alternative to a small AAC plant if your target market accepts non-autoclaved aerated concrete blocks and your production requirements do not specifically demand autoclaved aerated concrete (AAC).

Choosing between an AAC and a NAAC block production line depends primarily on the building materials your customers require, the applicable product standards, your available investment, and your expected production volume.

A NAAC block manufacturing process normally includes raw material batching, mixing, foaming, pouring, pre-curing, cutting, demolding, and non-autoclaved curing.

AAC blocks, in the strict technical sense, do require autoclave curing because autoclaving is part of the definition of autoclaved aerated concrete (AAC).

Choosing the right capacity is one of the most important decisions when setting up a NAAC block plant. A production line that is too small may limit sales growth, while an oversized plant can tie up capital before the local market is ready.

​For investors and building material manufacturers planning a lightweight concrete block project, curing technology is one of the key differences between traditional AAC and NAAC production.

Non-autoclaved aerated concrete (NAAC) is a lightweight cellular concrete produced through the same family of raw materials and foaming chemistry as AAC — cement, lime (or fly ash), sand, water, and aluminum powder — but cured at ambient or low temperature instead of in high-pressure steam autoclaves.
